Hi
Sorry for posting it in English. I am from NL and writing in Dutch and then translating to DE gives sometimes strange results... 😊
I have a 12kw 3phase hybrid lv, and starting with connecting self build battery packs. I have 1 pack finished, 16s with JKinverter bms, 15.26. So far all works ok, on vbatt mode and also fine on lithium(canbus communication). I have a micro inverter on the gen port of the Deye. Load port is open. Grid is connected to the Deye. House is between gridmeter en Deye.
Yesterday night I had nobatt selected. Last night i had the pack connected, but is was idle, not charging or discharging.
I see a difference of 100W! Battery connected is showing 100W more power from grid. 😖 Why? And how can it be reduced?
Yesterdaynight, nobatt
Last night, with battery
Wellcome.
Please slowly, the board has delay, dont double post please.

You have a PV inverter that can supply your entire house with uninterrupted power as a UPS system.
(This device will also do this fully automatically if a battery is connected)
If no battery is connected, the inverter switches off after sunset.
In terms of power consumption, you are therefore distinguishing between a UPS system that can supply your house with backup power within 4 ms and a PV inverter in sleep mode that waits for the sun to rise and does nothing else.
Where is your question again?
I have nothing connected at the loadport of my Deye.
When at night it uses 110W or more, doing nothing. Question is how can we reduce this self use power?
I read some option like grid voltage minimum set to 265v or so. I tried but then the Deye keeps clicking every 10 or 20sec or so, this is a relay clicking. I think its not a good idea to keep the relay switching the whole night... (i have set this in solarassistant)
